I'm considering a folding bike to improve my public transportation commute. Mostly I would use it for distances of 0-2 miles --- to the subway, on an errand, to the gym, to the other campus --- and I'd like to carry it up and down long staircases and in crowded subway cars, and I'll also have a backpack.
The problem is that many folding bikes are large and heavy for my height, 5'1" (61", 156 cm). Weight is an issue, too, but I suspect a well-designed shape could compensate for weight. I have also noticed that some folding bikes specify that they can't be used by anyone under 5'4" if they want their feet to touch the ground.
Can anyone recommend an inexpensive folding bike for me? Any short people who carry their folders on public transit, and can share their experiences?
I've been toying with the idea of an A-bike, but Chicago has poorly maintained roads and I'd like to hear of some alternatives.
Btw, it seems like some folding bikes could take advantage of their wheels and be rolled like a luggage cart, but I haven't seen any which do. Do such exist?
